In the 1940s, the possibility that drugs like LSD, psilocybin and MDMA could unlock and treat complex mental health disorders seemed near, but it took decades before work resumed on the study of the psychology, neuroscience, biochemistry and impact of these drugs. Now, we’ve assembled a team of neuroscientists, biochemists, clinicians and behavioral scientists to help you understand what we know today about the possibilities and risks of mental health treatment with psychedelic drugs.
